The IOC and WADA have raised the stakes over the past years with methods such as target testing or retesting of Olympic samples once new test methods are available.

Six athletes, including 1,500 gold medallist Rashid Ramzi of Bahrain, were caught doping at the 2008 Olympics in Beijing in retests of samples for CERA, the latest generation of the blood booster EPO.

'We are spreading the responsibility to the entourage of the athletes. We expect more pressure on the (athletes') surrounding and a raised inhibition level,' said Bach.

'The names would be passed on to state authorities in the case of doping violations, which could lead to criminal law and professional consequences.'

The plan is to be be discussed in detail at next week's IOC executive board meetings in Berlin. It is the latest step after the IOC decided in March to set up a watch list after each positive doping test in which the athlete's doctor and manager are listed.
